Solana NFT minting with candy machine/metaplex

Hello guys!
I need some help. I am finishing a website that will mint Solana NFT using candy machine/metaplex in a very simple steps. The model is that i would like to charge some fee added to the minting fee and not do what similar websites like Holaplex is doing when they add their wallet to the metadata as a creator fee.
Does anyone can help with letting me know if this is something possible to do? any pointers on some info on that possibility ? Would very much assist!
Thanks guys!
